This invention relates to cameras operable to select one film supply system from either a normal wind-up system or a preparatory wind-up system. The camera has a selector switch for selecting one of the film supply systems, and an inhibiting means for inhibiting that the two systems are applied to one film by the switch, a write means for recording selected information onto a film or a storage device provided in the cartridge, and a read means for reading the selected information and the frame information written in the device. The switch selects a film supply system which is indicated by the selected information read out from the device of the loaded film by the read means. Additionally, a film supply means is provided for preparing and supplying the film in accordance with the frame information read out by the read means. The film supply means can wind up the film to supply even when either of the two film supply systems is set. The selection of the film supply system can be changed by the switch only before the first frame is photographed. A counter is provided for inhibit that the first frame of the film is supplied to the photographing position more than predetermined times in response to the change in the film supply system selected by the switch.

The battery check device for cameras comprises a counting device for counting the number of times photographing is performed by cameras, a detecting means for detecting the remainder of the capacity of batteries, and a determining device for determining the number of the remaining pictures which can be taken on the basis of the detected remainder of the capacity of batteries.

Battery check device for cameras

A camera system has a device for recording an image of a photographing field in a recording medium such as a photographing negative color film, a photometering device for forming brightness information concerning the brightness of the photographing field, and a color information forming device for forming, in accordance with the brightness information, color information concerning the color of the light from a light source for illuminating the photographing field. The printing process after the deployment of the image is executed with a suitable control of the printing exposure light quantity in accordance with the color information so that a color print of a good quality can be obtained with a high reproducibility of the color.
